Ok right now i have a rebuilt 90' ka24e with 55k...i have injen short ram and im going to purchase the cold extension...i also have a custom exhaust with those two mods im guessing about 150 mabe a little more the rear wheels. im also going to get the JWT ecu, hotshot headers, msd 6a ignition control, magnecor 8.5 mm wire set and ngk sparks. would these mods allow me to reach the 200 level and am i going theh right path. i was also think about getting cam and or ported pistons

Highly doubt the 150 claim, maybe 130, as we've all seen what the KAs are capable of with various mods. For everyone's sake use the search function, the 200 mark has been discussed heavily for a long time now.

Ignition is not really neccesary as you still run off pump gas, just some good plugs and wires would do you good enough, for your goal of 200HP, you can not forget CAMS, pulleys, increased compression, Head work, exhaust and a wide variety of modifications your can do.

They make a JET chip for your 240. its the best ecu that i have seen. also, how about going full catback, it really help alot. definatly need to get some headers, maybe even a fuel regulator. I went headers, cams, catback, nitros, flywheel, and clutch, and was at about 220hp. so there is plenty you can do, even if you dont wanna run n20. Youll notice a pretty big increase in power with a 9-11 pound flywheel. Hit me back with your response.

DP Race Team: yeah im trying to stay away from n2o as much as possible who much is the jet ecu and where can i find suitable cams for my sohc? i tried searching several jdm stores, but since the ka is not a jdm motor i guess i was looking in teh wrong area!

Im hoping to have somewhere in the neighborhood of 160-180 RWHP with my setup:

10.5:1 compression JE Forged pistons (being installed right now)extremely mild exhaust side head porting (did it myself with a dremel tool)

plus everything in my sig. Without changing your bottom end and reworking your head, a SOHC will never see 200 RWHP with bolt on anything (except Turbo or N20).

if i were you i would get a ka24de and swap that in as it is a much better platform to start with. you can get them pretty cheap at salvage yards i hear. I'll be selling my ka24de feb or march if anyone wants to hit me up with an offer. (its in excellent condition)

I beg to differ, i think that the ka24e is a very good engine. There is a large All motor aftermarket (alot it offered from nismo), it has same if not more Hp after the same mods, (the stock CR for the ka24de is 9.5 to 1 and the stock for the ka24e is 8.6 to 1 so that is were most of the Hp is different in stock form) Flow rates are simialer after port and polish, and lastly If i were planning to make an all motor engine i would use the Ka24e, but to each to his own.

A twin cam has no actually advantage to a SOHC. Many people think it does but really it doesn't. There is direct lift that is better than rocker arm, but there is only one cam to turn and not 2 (theortically if you build 2 engines identical to one another with the ONLY diffence being the SOHC and DOHC they should have they same power). I really havn't looked for parts for the ka24de, but i'm sure you can find parts for both engines if you look hard enough. IMO i think that the Ka24e is more cost effective, you only need 1 cam, 12 valves, 12 P&P's. The biggest disadvantages is the 12 valves to 16 valves, but as i said that after P&P the flow rate is the same.

i agree with you for the most part, like you said its about prefrence. and im not dissing the ka24e because as far as im concerned all nissan motosr are capable of going above and beyond what other manufacturers make. Its just as far as bold on and other light mods the twin can is a bit better. And im pretty sure that higher compression is better for all motor aplications.

a DOHC engine has more manipulation settings because you can time the intake and exhaust cams seperately, and also, the flow characteristics tend to be smoother with a DOHC.the 2 intake and 2 exhaust valves flow more air overall, or at least, have the potential to flow more because you can fit the cylinder better with 4 small circles(the valves) than with 2.
